[Docket No. 96-NM-79-AD; Amendment 39-9890; AD 97-02-06]
RIN 2120-AA64
Airworthiness Directives; Fokker Model F27 Mark 050 and F28 Mark
0100 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Fokker Model F27 Mark 050 and F28 Mark 0100
series airplanes, that requires installation of a bonding cable for the
housing of the lavatory pump and filter assembly and the lavatory bowl.
This amendment is prompted by a report indicating that the housing of
the lavatory pump and filter assembly is not grounded properly. The
actions specified by this AD are intended to prevent such improper
grounding, which could result in an electrical fire and/or injury to
passengers and crewmembers.
DATES: Effective February 27, 1997.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of February 27, 1997.
ADDRESSES: The service information referenced in this AD may be
obtained from Fokker Services B.V., Technical Support Department, P.O.
Box 75047, 1117 ZN Schiphol Airport, The Netherlands. This information
may be examined at the Federal Aviation Administration (FAA), Transport
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton,
Washington; or at the Office of the Federal Register, 800 North Capitol
Street, NW., suite 700, Washington, DC.

Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Fokker Model F27 Mark 050
and F28 Mark 0100 series airplanes was published in the Federal
Register on October 1, 1996 (61 FR 51255). That action proposed to
require installation of a bonding cable for the housing of the lavatory
pump and filter assembly and the lavatory bowl.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
The commenter supports the proposed rule.
Conclusion
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 48 Model F28 Mark 0100 series airplanes of
U.S. registry will be affected by this AD, that it will take
approximately 6 work hours per airplane to accomplish the required
actions, and that the average labor rate is $60 per work hour. Required
parts will cost approximately $209 per airplane. Based on these
figures, the cost impact of the AD on U.S. operators of Model F28 Mark
0100 series airplanes of U.S. registry is estimated to be $27,312, or
$569 per airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted.
Currently, there are no Model F27 Mark 050 series airplanes on the
U.S. Register. However, should an affected airplane be imported and
placed on the U.S. Register in the future, it would require
approximately 2 work hours to accomplish the proposed actions, at an
average labor rate of $60 per work hour. Required parts would cost
approximately $88 per airplane. Based on these figures, the cost impact
of this AD on Model F27 Mark 050 series airplanes would be $208 per
airplane.
Regulatory Impact
The regulations adopted herein will not have substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government. Therefore, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a
significant economic impact, positive or negative, on a substantial
number of small entities under the criteria of the Regulatory
Flexibility Act. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:

altered, or
[[Page 3449]]
repaired so that the performance of the requirements of this AD is
affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (b) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent improper grounding of the housing of the lavatory
pump and filter assembly, which could result in an electrical fire

following:
(a) Within 6 months after the effective date of this AD, install
a bonding cable for the housing of the lavatory pump and filter

compliance time that provides an acceptable level of safety may be
used if approved by the Manager, Manager, Standardization Branch,
ANM-113, FAA, Transport Airplane Directorate. Operators shall submit
their requests through an appropriate FAA Principal Maintenance
Inspector, who may add comments and then send it to the Manager,
